Dedicated to the balanced discussion of global warming
Thomas Paine’s Corner – April 8, 2007
This blog article discusses the documentary “The Great Global Warming Swindle”. While I have not had the opportunity to watch this program, I think that the article does a fair job of critiquing the facts portrayed. It pains me when articles and shows don’t make sure that they have data absolutely correct regardless of what their stance is. Since it is my contention that we need to fully evaluate all of the data, not having the facts straight is detrimental to the cause.
However, some of the primary data used in TGGWS comes from Dr. John Christy, the same scientist that was found to have flawed data when using weather balloons to measure the temperature of the troposphere. When the upgraded satellites were again used to measure the temperature of the troposphere, it was found that the discrepancies in the old readings were to the negative and the troposphere was actually warmer than measured.
The source of this data was given to be NASA. The Independent inquired into this graph and “received an email through Wag TV’s PR consultant saying that the graph was drawn from a 1998 diagram published in an obscure journal called Medical Sentinel. The authors of the paper are well-known climate skeptics who were funded by the Oregon Institute of Science and Medicine and the George C Marshall Institute, a right-wing Washington think-tank.”
The writer/director of the film, Martin Durkin, admits to changing the C4 graph.
….Other graphs used in the film contained known errors, notably the graph of sunspot activity. Mr Durkin used data on solar cycle lengths which was first published in 1991 despite a corrected version being available – but again the corrected version would not have supported his argument. Mr Durkin also used a schematic graph of temperatures over the past 1,000 years that was at least 16 years old. This graph gave the impression that today’s temperatures are cooler than during the medieval warm period. If he had used a more recent, and widely available, composite graph it would have shown average temperatures far exceed the past 1,000 years.
I do not know where the sunspot chart data used in the film was acquired, but the chart from NASA looks nothing like their chart and therefore does not even come close to the global temperature chart that we have already shown to be inaccurate.
